Serial No. 19,921. (No model.)

To all whom it may concern,.-

Be it known that I, CHARLES JOSEPH LAN- GENBACH, a citizen of the UnitedStates, re-` siding at Independence, in the county of Buchanan and Stateof Iowa, have invented a new and useful Windmill, of which the fol ylowing is a specification.

The invention relates to improvements in' windmills. v

One object of the present invention is toy improve the construction ofwindmills and to provide a simple and comparatively-ineXpen-- sive oneadapted to dispense with a vane and capable of holding the wind and ofobtainingl [5 a maximum effect therefrom.

Al further object of the invention is to provide a wind mill of thischaracter which will be perfectly balanced and which will automaticallygovern itself and at the same time zo be adapted to be readily throwninto and ou`tl 4of operation by hand.

The invention consists in the construction.

and novel combination and arrangement of parts hereinafter fullydescribed, illustrated z5 in the accompanying drawings, and pointedoutin the claims hereto appended. f

In the drawings, Figure 1 is a verticalsectional view of a windmillconstructed in ac-` cordance with this invention. Fig. 2 is a detailview of the wind-wheel, one half the blades being arranged in positionto be operated on by the wind and the other half being arranged out ofoperation. Figs. 3 and 4 are detail views illustrating the constructionfor 3 5 transmitting motion from the vertical shaft to the pump-rod.

Like numerals of reference designate corresponding parts invall thefigures of the drawings.

1 designates a tower provided at its top withy antifriction-rollers 2,arranged horizontally and receiving a rotary frame 3, which is providedwith upwardly=extending arms 4'and 5, having bearings 6 and 7 for ahorizontal Wind- Wheel shaft 8, and the latter extends from the rotaryframe in both directions and carries at one end a Wind-wheel 9, and ithas a counterbalancing-Weight 10 at its other end, whereby the windmillis perfectly balanced and all vannular anges 14 and 15, from whichextend arms 16 and 17, forming supports for pivoted .blades 18, arrangedat an acute angle to the horizontal wind-wheel shaft and 'adapted tocollect the wind. The inner arms 16, which are secured 'at their innerends to the inner annular flange 14, are arranged at right angles to thehorizontal Wind-wheel shaft, and they are provided at ther outer endswith angularly-disposed eyes 19,Which receive pintles 2O for hinging orpivoting the outer ends of the blades to the arms. The pintles 20, whichmay consist of bolts, pins,or any othersuitable fastening devices, alsopass through eyes of straps 2l, which are arranged at opposite sides ofthe eyes 19 of the arms 16. The blades are provided at their innerendsWith longitudinal pintles 22, which are arranged ineyes or openingsof a bearing-ring 23, which is supported by the arms 17 of the outerflange l5 and by braces 24, extending from the ring to the inner flange,as clearly shown in Fig. l of the accompanying drawings. The blades bybeing arranged at an acute angle to the shaft form a tapering lspacewithin them and are adapted to gather and hold the Wind, and each bladeis provided with a series of transverse slots or openings 25, arrangedat an angle, as shown, and adapted to permit currents of air to passthrough the blades, and thereby enable the Wind to obtain a hold orpurchase on the sanne. The blades which 'are pivoted in this manner areadapted to ,be partly rotated to expose their faces to the wind and toarrange them edgewise to permit the wind to pass through 'the wind-wheelWithout rotating the same. This pivotal movement of the blades iseffected automatically by means of a weighted lever 26, which isconnected by a coupling 27 with a series of rods 28, connected at theirouter ends eccentrically of the blades,

near the inner ends thereof, as clearly shown in Fig. 1. The blades areprovided near their inner ends with eyes 29, receiving pintles 30, whichpass through perforations or eyes of the outer ends ofthe rods 28, andthe inner ends of the latter are connected with a flange or disk 31 of asection 32 of the coupling 27. The coupling 27 is composed of the saidsection 32 and a section 33, the section 32 being provided with theenlarged flange or disk 31 at one end, and it has a small annular flange34 at its other end, and this small annular flange is received within anannular groove 35 of the section 33, whereby the section 32 is adaptedto rotate within the section 33. The periphery or outer edge of theenlarged flange or disk 3l is bent or set at an angle to receive theinner ends of the rods 28, which are threaded for the reception of nuts36, arranged .in pairs and located at the opposite faces of the flangeor disk 31. The inner section 33 is connected by a link 38 with one arm3S) of the lever 26, which is substantially T-shaped, being fulcrumed at40 on a suitable support 41, extending from the adjacent arm 4of therotary frame. The arm 39, which is one of the transverse arms of thelever, extends upward from the bracket or support 4l to a point abovethe horizontal wind-wheel shaft, and the other transverse arm 42 extendsdownward from the bracket or support. and is attached to a flexibleconnection 43, which passes over a guide-pulley 44 and extends downwardto a sliding collar or sleeve 45. The sliding collar or sleeve 45, whichhas the lower end of the iiexible connection attached to it, isslidingly mounted on the depending tube 11 and is provided with a pairof horizontal annular flanges 46, forming an annular groove in whichextends a pin or projection 47 of a weighted lever 48. The weightedlever 48, which is fulcrumed between its ends on the tower, is providedat its outer end with a weight, and its other end is attached to aflexible connection 49, designed to extend to the base of the tower, sothat the windmill may be controlled by hand. The pin or projection 47,which engages the annular groove of the sliding collar, is located at apoint between the fulcrum of the lever and the flexible connection 49;but any other form of connection may be employed. The weight of thelever 48 is adapted to assist in sliding the collar upward after theflexible connection 49 has been slackened or released to start thewindmill.

The horizontal wind-Wheel shaft has keyed or otherwise secured to it apair of verticallydisposed bevel gear-wheels 51 and 52, provided attheir inner opposite faces with teeth and meshing with a pair ofhorizontal pinions 53 and 54, mounted, respectively, on the upper end ofthe vertical shaft 12 and on a vertical counter-shaft 55. The horizontalpinions 53 and 54 are provided with lower vertical spurteeth and meshwith each other, and they have upper inclined teeth forming bevel-gearfor meshing with the vertically-disposed bevel gear-wheels 51 and 52.This double arrangement of gears is adapted to prevent all side draftand insures a smooth easy motion instead of the rough jerking movementcommon to many Windmills.

The weight 10, which is of conical form, consists of a solid outerportion and a hollow inner portion forming a tapering sleeve orextension 56, which forms a continuation of the outer face of the solidportion of the weight 10 and which is extended suiliciently to form ashield for the gearing to prevent the same from obstructing the force ofthe wind. The conical weight is adapted to deiiect-the wind against theblades of the funnel or cup shaped Wind-wheel. The adjacent end of thehorizontal shaft 8 extends through the inner hollow portion or sleeve ofthe conical deiiecting weight and is received within a socket 7 and issecured within the same by means of a set-screw, as clearly shown inFig. 1. The weight, besides serving as a shield or deiiector, is adaptedto counterhalance the wind-wheel, and it coperates with the doublearrangement of gears in balancing the windmill and in preventing sidedraft.

The lower end of the vertical shaft l2 is provided with a horizontalpinion 59, which meshes with a vertical gear Wheel 60, as clearlyillustrated in Fig. 3 of the accompanying drawings. These gears 59 and60 are preferably beveled, as shown, and the vert-ical one is mounted ona horizontal shaft 61, which carries a vertical sprocket-pinion 62. Thesprocket-pinion 62 is connected by a sprocket chain 63 with aneccentricallymounted sprocket-wheel 64, which is adapted to oscillate ahorizontal lever 65. The horizontal lever 65, which is fulcrumed at oneend, is provided at its other end with au opening or bifurcation 66 forthe reception of the eccentrically-pivoted sprocket-wheel 64, and as thelatter is rotated the horizontal lever will be oscillated. Thehorizontal lever is adapted to reciprocate a pump-rod 67, which ispivoted at its upper end to the horizontal lever at a point between theends thereof. The weight of the pump-rod holds the chain or belt taut,and the stroke of the pump-rod is adjusted by means of a series ofperforations 68, located at different distances from the center of theeccentrically-mounted gearwheel 64 and adapted to receive the pivot G9of the upper end of the pump-rod.

In order to guide the outer section of the coupling 27, it is providedwith a pair of guide-rods 58, secured to the enlarged liange or disk 3lby nuts and extending through suitable openings or perforations of theinner ange 14.

It will be seen that the windmill is simple and comparativelyinexpensive in construction, that there is no side draft, and that whileit is automatic in its operation it is adapted to be readily thrown intoand out of operation by hand. It will also be' apparent that the bladesform a funnel or cup-shaped Wind-Wheel and that the slots or openings ofthe said blades permit currents of air through the same, and therebytend to hold the Wind on the faces of the blades. Furthermore, it Willbe apparent that the conical defiector formed by the Weight andthetapering tubular extension is adapted to direct the Wind clear of thegearing and against the blades, so that the latter will receive thaefull force and effect of the Wind.

It will also be clear that a simple and eective device is provided fortransmitting motion from the vertical shaft 12 to thevertically-reciprocating pump-rod,which is located beneath the shaft,and that the stroke of the pump-rod may be readily Varied, and that theWeight of the said pump-rod retains the chain or belt in engagement withthe eccentricallymounted wheel of the oscillating lever. Also thisdevice may be mounted at any point on the tower and can be arrangedclose to the bottom thereof, so as to he readily adj usted.
